Abstract (en)

This application relates to a multi-piece enclosure for a portable electronic device (102, 104, 106). The enclosure includes a metal part (240) including a metal substrate (204) and a metal oxide layer (206) overlaying the metal substrate (204), the metal oxide layer (206) having an external surface (202) that includes openings that lead into undercut regions (WU). The openings are characterized as having a first width, and the undercut regions (WU) are characterized as having a second width that is greater than the first width. The enclosure further includes a non-metallic bulk layer (252) including protruding portions that extend into the undercut regions (WU) such that the non-metallic bulk layer (252) is interlocked with the metal part (240).
